Samsung Galaxy S II on sale for $199.99 with a free generic car charger and gel skin and free shipping. This is a great deal on Samsung's late 2011 flagship. The phone still sells for over $400 at t-mobile.com and the best previous price I've seen on it was $349.99 at Walmart with a free $50 top up card included.
Even though it's a year and a half old, the Galaxy S II can still run rings around 99% of prepaid Android phones thanks to a dual core 1.5 Ghz Snapdragon processor, 42 Mbps HSPA+, and what's generally considered the best 8MP camera on any Android phone.
The T-Mobile version of the S II comes with ICS, but an official Jelly Bean update is available through Kies. If you're into rooting and ROM'ing, the S II is easy to root and has a large, active development community and dozens of recent ROMs to try out.
The HSN deal is listed as being "for a limited time only" which means it could end at any time. So if you want it do not hesitate to visit hsn.com and get it now.
Update June 6, 2013: HSN has raised the Galaxy S II price ro $219.95.
